/* ** ** Swift/XRT hardness ratio for Mrk 421. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 58109.419341 0.000359 0.25110 0.00903 1.00000 0 69.54755 1.11650 63.67187 1.02216 17.46353 0.56177 15.99110 0.51432 58109.420073 0.000373 0.24769 0.00889 1.00000 0 66.80908 1.07038 61.98141 0.99303 16.54791 0.53160 15.35385 0.49322 58109.420825 0.000379 0.23718 0.00848 1.00000 0 68.43354 1.07083 63.68530 0.99653 16.23129 0.52213 15.10509 0.48590 58109.421586 0.000382 0.24125 0.00866 1.00000 0 66.70698 1.05587 62.07784 0.98260 16.09301 0.51840 14.97641 0.48243 58109.422321 0.000353 0.25389 0.00916 1.00000 0 68.58756 1.11324 63.82563 1.03595 17.41381 0.56143 16.20500 0.52246 58109.423047 0.000373 0.24771 0.00882 1.00000 0 67.26263 1.07229 62.59180 0.99783 16.66161 0.53019 15.50437 0.49337 58109.423863 0.000443 0.24475 0.00806 0.99388 0 67.98223 0.99298 63.02073 0.92049 16.63893 0.49118 15.42440 0.45531
